My first RGB Jupiter
Finally there was a period of clear sky last night and I took the chance to test my newly fabricated RGB equipment and obtained two photos for comparision.
A picture is worth a thousand words. From the attached picture the left one is a L-channel single shot while the right one is a RGB combined shot. It is very obvious that RGB image has better resolution and higher contrast than a mere L-channel image, under same sky conditions.
The stability last night was very poor but the test showed that RGB imaging has much better potential than pure L-channel or a Bayer color sensor.
Camera :- ZWO ASI174MM
RGB :- 0.009 sec exposure each for 3000 frames.
L-channel :- 0.009 sec exposure for 3000 frames.
Telescope :- C-11 working at f/25
Filter wheel :- DIY remote control filter changing. Original is a ZWO manual filter wheel.
Filters :- RGB interference filter from ZWO.
Mount :- CPC1100 robotic.

- The left image is a single shot by the camera ( L-channel) while the right image is a RGB combined color image. It is obvious that RGB imaging has higher resolution and contrast than a single shot B/W picture.

前天晚上終於開天,又可拍攝木星,雖木星衝已過,今晚木星上也有特别現像出現*雙衛星凌木*,在大氣擾動很不穩下拍攝了此現像記錄。
